Great use of the "hard reset" theme! It took me awhile to figure out how the grappling mechanic worked. The music resetting every time you collected a battery did get a bit grating. I didn't realize the green particles were enemies until a few attempts as the game is very busy visually and lacking visual and audio feedback when you take damage outside your health draining. Adding sound effects when you use your grappling hook, collect batteries, or take damage would improvement the overall experience. I don't want to come off as too critical as I did reattempt my descent several times and found it challenging although sometimes not in a good way. With some small improvements it could be a lot better but what's there is a good foundation!
